EMBOSSING-MACI-IINE.

. To all whom it may concern:

"Massachusetts, have invented a certain new and useful Improvement inEmbossing-Machines, of which the following is a specification, referencebeing had therein to the acings, in whichcompanying drawings. u

The invention comprises various improve- .ments in embossing or printingmachines.

The said improvements are designed more particularly for use inembossing or prlnt ng in gold, silver, and other transfer material,including color, upon leather and other material, as for instance uponparts of shoes and upon hat bands, belts, stays, and the like, althoughthey are not necessarily restricted to such use in all cases. Theinvention includes various novel combinations and features ofconstruction.

.The improvements comprised in the invention are illustrated in aconvenient form ofembodiment in the accompanying draw- Figure 1 is aside elevation, partly broken away, of a machine containing the saidembodiment.

Fig. 2 is a front elevation of the said machine.

Fig. 3'is a rear elevation thereof.

Fig. 4 is a view in vertical section mainly in the plane indicated bythe line 4, 4, of Fig. 2.

Fig. 5 is a view similar to Fig. 4 but show ing the ram closed againstthe die.

Fig. 6 is a view of the lower feed-roll and its shaft or arbor, with thesaid roll in longitudinal section.

Having reference to the drawings,-

The illustrated machine is shown constructed with a frame comprising abase 1 and opposite parallel vertical side-cheeks 2, 2. The operatingshaft 3 of the machineis. mounted 1n bearings in connection with thesaid cheeks. In practice, the said shaft will have combined therewithsuitable driving connection and start-and-stop devices arranged toenable the machine to he started at'the will of the operator, and tocause the same to stop automatically at the end of a single rotation ofthe shaft 3, substantially as in the case-.of various known machines.The more important parts of the machine include the presser or rams andmeans for Specification of Letters Patent.

operating the same from the shaft 3; the die 5 coiiperating with thesaid presser or ram to make the impression or imprint, a heater 6 (Figs.4 and 5) in connection with the said die, guides at A and B for thestrip, a, of transfer material, which are located respectively at thearriving side of the ram and die and the departing side thereof, apulhofi device 7 (Figs. 1, 3, 4 and 5) for facilitating the advance ofthe said strip to the working point and through the machine, andfeedrolls 8, 9, for the strip.

As shown in Figs. 1, at and 5, the die 5 is fixed to the under side of aforwardly projecting portion ofa die-support 5 that is secured at therear of such portion by bolts 5, 5 to the tops of the cheeks 2, 2, ofthe machine-frame. Thereby the die is mounted in position to cooperatewith the movably mounted ran14. The space around and in front of thesaid forwardly projecting portion of the die'support, and the die, isclear and unobstructed so as to permit the article or material which isto be embossed or printed tobe presented and applied from the front inposition for'the embossing or printtion, inasmuch as it permits therequired portion of the work to be passed in between the die and the ramby an upward and rearward movement, and other portions thereof to hangdown in front of the ram and the adjacent parts of the machine.

The mannerand means of attaching the die 5 to the die support 5 may varyin practice. In the present instance it is shown as having its backplaced against the under face of the forwardly projecting portion of thedie-support 5 and as belng clamped in place through being engaged at itsends by downwardly projecting portions of flanges formed on screws 5*,5*, Figs. 1 and 2, the stems of the said screws entering threaded holestapped in the opposite sides of the said portion of the die-support. Forconvenience insetting orpOsitioning the die upon the 110 2 die-support agage 5", Fig? 1,\is applied to the said portion of the die-support atthe rear of the placefor the die. The said gagecombined therewith theheater 6. The latter is in this instance an electric heater, al-' thoughthe precise character and construction of the heater is not in all casesmaterial, and I contemplate in practice varying the character,construction, and manner and place of application-of the same. As hereinshown the electric heater 6 is contained within a chamber in thedie-support, Figs.

4 and 5, the wiring for the heater being in-' dicated at 6. Thedie-support is made of heat-conducting material, so that the heat mayreach the die attached thereto, and for the purpose of preventing lossand waste of 80 heat by conduction to the machine-frame heat insulatingmaterial 6 is interposed between the die-support'and the portions of thecheeks 2, 2, to which said'die-sup ortis applied, washers of suchmaterial (shown 85 best in Fig. 1) also being interposed between theheads of the bolts 5 and the upper surface of the die-support. Asuitable switch and rheostat (not shown) will be included in theelectric connections of the 40 heater in practice for the purpose ofcontrollin the heating and the degree of heat.

he closing together of the ram and die for the embossing or printingoperation, and subsequent separation and opening to. permit removal ofthe embossed work or material are provided for by mounting the ram upona movable support and operatively combining the said support with aneccentric upon the operating shaft 3. In addition, provision is made fora yielding action of the ram in closing toward the die. The illustratedmachine embodies ram-supporting and actuating devices arranged toprovide for the said yielding action and embodying certainof theimprovements which are comprised in the present invention. A differentconstruction and arrangement of the actuating devices may be provided inpractice, in case it should be deemed advisable to simplify theconstruction and reduce cost, or meet special considerations and requirements in use, or in accordance with the views and wishes of thebuilder or purchaser of the machine. The ram 4 is shown sleeved upon oneend of a post or stem 4 having the at 5 to accom-' main portion of itslength contained within an elongated socket in a carrier 4 constructedwith a strap 4 encircling the eccentr c 4 on the operating shaft 3. Theeccentric 1n its rotation gives a reciprocatory movement to-the carrier4", which carries the post 4 4 and ram with it in its movements, therebycausing the ram to alternately approach the die and recede therefrom. Toguide the ram in its movements a radius arm or lever 4", which is hungby means of a pivotal shaft 4 between the upper portions of the checks2, 2, is connected pivotally at 4' with the ram, as shown in Figs. 1, 4and 5. The said radius arm or lever 4 is of open framework construction,with the forwardly projecting ends of its side-portions arranged so thatthey. receive between them a rearwardly projecting lug of the 'ram, thepivot 4 being engaged with the said ends and the lug as 35 shown. Tosecure the yielding action of. the ramin pressing the work against thedie, the post 4 by which the ram is more immediately supported is mademovable within the socket of the carrier 4 and a cushion ing means iscombined therewith. This cushioning means comprises in the presentinstance a spring-controlled rocker or lever 4 which is hun or pivotedat 4 in the lower part of the carrier 4, it having a toe 4 which 5engages with the inner end of the post 4. The controlling springtherefor is an expanding spiral spring 4 that is confined etween thefree extremity of the lever or rocker 4 and an adjacent portion of thecarrier 4 the opposite ends of the said spring being seated in pocketsthat are formed in the said end of the lever and in the said portion ofthe carrier respectively. The spring by its tendency to expand actsagainst the lever or rocker 4 so' that the toe 4 of the latter serves tosupport the post 4 and the ram 4, with the ram in its outward positionrelative to the carrier. \Vhen the thickness of work intervening betweenthe ram and the die is such as to oppose sufiicient resistance to theclosing movement of the ram to overcome the tension of spring 4*,thesaid spring yields and permits the lever or rocker 4" to turn on itspivot 4 relative to the carrier 4 To'enable the cushioning effect to bevaried to meet requirements in practice, provision is made foradjustment of the tension of the spring 4". The means of adjustmentcomprises a'pin or stud 4 which is fixed by one end'to the carrier 4 atthe center of the spring-receiving cup on the carrier and projectsthrough ahole in the lever or rocker 4" formed 'concentrically with thespringreceiving pocket'of the said lever or rocker.

The spring 4* [surrounds the intermediate portion of the-said pin orstem. The portion of the; pin or stud which projects at the front of'thelever or rocker 4 is screwthreaded and has applied thereto adjust- 1.30

ment and check-nuts a", a". By backing oil the said nuts the said springis permitted to expand more or less and thereby its tension is reduced,while by turning the said nuts inward along the pin or stud 4 so as tocorn press the spring more or less the tension of the spring isincreased. Adjustability of the ram upon the post 4*? toward or from thedie to suit the thickness of the work is secured by screw-threading theouter portion of the said post and applying thereto a nut 4 andconnected gear 45*, shown best in Fig. 1, the said nut and gear servingas a collar to fix the position occupied by the sleeve of the ram uponthe post. By turning the nut around the post, it and the ram are shiftedlengthwise of the post. To provide for conveniently turning the nut byhand, a pinion 4* is mounted alongside the nut-gear 4 and in engagementtherewith, this pinion having a thumb wheel 4 which enables it to beturned manually for the purpose of rotating the nut 4. The pinion 4 andthumb wheel 4 are mounted upon the carrier 4 by means of a journal 4!projecting from them and entering a bearing in a projecting portion ofthe carrier, in which hearing it is retained by means of the inner endof a screw 4, the said end entering an annular groove around thejournal. To prevent the post from rotatingwhile the adjustment nut isbeing turned, a screw 4* is applied to the side of the said post, itsend projecting from the post into a longitudinal slot 4 formed in'thecarrier 4". This slot permits the post to move lengthwise within thesocket of the carrier as the spring 4 yields under the closing pressureand expands when such pressure is relieved.

Suitable back-stops or gages 10, 10, are combined with the ram 4, atopposite sides thereof, to determine by engagement with the rear edge ofithe work the proper position of the work when applied to the face ofthe ram. Each of these gages or backstops has a body-plate whichis'applied to the corresponding end or side of the ram and attachedthereto by means of screws 10, 10, the said plate being slotted at 10 topermit the gage or back-stop to be adjusted in the direction from frontto rear or vice versa.

The strip a of transfer material passes from the source of supplythrough the guide-system A, past and in engagement with the pull-off '2,then forward between the ram 4 and die 5, to and around the curvedportion of a guide 11 adjacent the die, then rearward through theguide-system B, and then between the feed-rolls 8 and 9.

The guide-system A is located at the supply-side of the die and ram. Itincludes a aching-plate 12, which occupies an upwardly inclined positionand serves to support the strip a as the latter passesthrough the saidguide-system. The guide-system A also includes edge-guides 12 12, forthe strip which are shown best in Fig. 3. The said edge-guides arelocated at opposite sides of the path of the strip a. They areadjustable toward and from each other to suit dilferent widths of strip.With the edgeguides are combined means for holding them in parallelismwith each other, maintaining them in parallelism in all positions ofadjustment, and keeping them securely in their adjusted position. Tohold the edge-guides l2, 1 in their working positions and parallel witheach other, as well as maintain them in parallelism in the dif ferentpositions of adjustment, each edge' guide is connected with the plate 12by a pair of parallel-motion links 12 12,- shown best in Fig. 3.Movement of the edge guides in the direction of their length will causethe parallel-motion links to swing about the points of pivotalconnection with the plate 12, with resulting shift of the edge-guidestoward or from each other, according to the direction or" movement.Thereby the adjustment of the edge-guides for varying the distancebetween them to suit the width of the strip a is efi 'ectedv To insuremovement of the edge-guides in uni son and cause them to move inward oroutward simultaneously and to the same extent in being adjusted, the twoedge-guides are connected by means of links 12, 12, in other convenientmanner, with an inter mediately located longitudinally arranged bar 12This bar is mounted conveniently in position by being supported uponcrossbars 12 12 which in this instance respectively lie upon the upperand lower ends,

respectively, of the edge-guides 12, 12 The cross-bars 12 12 are held inplace by means of screws l2, 12', the stems of which pass through holesin the opposite ends of the said cross-bars and enter threaded holesthat are tapped in the marginal portions of the plate 12. Thelongitudinal bar l2 is held in place upon the cross-bars 12 12 by meansof screws 12 12, the stems of which pass through longitudinal slots 12,1 12, in the bar 12 and enter threaded holes in the cross-bars 12 12 Theslots i2, 12*, provide for longitudinal shift of the bar 12 and thuspermit of the adjustment of the edge-guides toward or from each other.After having beenadjusted, the edge-guides 12, 12*, may be securelyfixed in place, either by tightening the screws 12 12*, so as to clampthe bar 12 to the cross-bars 12 12 and thereby hold the bar 12 fromlongitudinal movement, or, without tightening the said screws 12, 12',by tightening the screws 12, 12*, so as to cause the crossbars 125,12 topress upon the edge-guides 12, 12, and clamp the latter firmly againstthe outer surface of the backing-plate 12. This latter mode of holdingthe edge-guides in their adjusted position has the advantage that as aresult of the edge-guides being clamped firmly against the surface ofthe backing-plate 12 1t is renderedimpossible for either edge. of thestrip a to enter between one of the edge-guides and the saidbacking-plate. When it is desired to adjust the edge-guides toward orfrom each other, it is of course necessary that the pressure of thecross-bars 12 12 upon the edge-guides should be sufiiciently relaxed topermit the edge-guides 'to slide beneath the cross-bars, and that theadjustment bar 12 should be free to slide longitudinally. The

"upper portion of the backing-strip 12 is curved forward toward the dieand ram to provide a curved guiding surface for the strip a as itchanges direction in leaving the guide-System A.

Between the guide-system A and the pulloif 7 the strip a is engaged by adevice 13 which serves to take-up the slack in the portion of the stripwhich is passing through the machine. Thereby the strip is maintained atuniform tension within the machine, and uniformity in the extent towhich the strip is advanced relative to the die at each feed-movement ofthe feed-rolls is insured. This take-up 13 in the present instance is inthe form of a swinging bail comprising a transverse portion which restsupon the strip adjacent the curved upper portion of the backing-plate,and side-arms which are engaged pivotally with lugs 12, 12, upon theupper portion of the said backing-plate. The said bail rests by itsweight upon the strip between the pull-ofi and the point at which itleavesthe backing-plate 12, and operates to maintain the strip uniformlytaut. When the working of the parts tends to slacken the portion of thestrip that is passing through the machine the bail swings so as to forma bend in the strip between the backing-plate 12 and the pullofi',.thustaking up the slack and maintainingthe strip at substantially uniformtension. In practice, a slight drag is applied to the strip before itarrives at-the take-up device, whereby the strip is held back at thesupply-side of such device so that the latter operates effectively totake-up the slack arising within the machine as far as the feedrolls.This drag will be produced by applying in any convenient manner a slightresistance to oppose the travel of the strip from the'source of supplythrough the guidesystem- A. I have herein shown provision for creatingand applying the said drag in the form of a small weight, 13, Fig. 3,resting upon the strip adjacent the lower crossbar 12 A continuation ofthe curved guide 11, extending upwardly and rearwardly above the die anddie-support, constitutes a backing-plate for the guide-system B. Thelatter, as shown best in Fig. 2, corresponds in general constructionwith guide-system A, and comprises the parallel edge-guides 11, 11,parallel-motion links 11", 11", etc., connecting-links 11, 11,adjustment-bar 11 slotted at 11, 11, screws 11, 11, and transverse-bars11 11. The upper-end-portion of the guide and backing-plate 11 is curvedtoward the entrance between the feed-rolls 8, 9, to provide for agradual change of direction of the strip as it passes from guidesystem Bto the feed-rolls.

The feed-rolls 8, 9, are located at the rear of the guide-system B,adjacent the curved end of the backing-plate 11. The shaft 8- of thefeed-roll 8 is mounted in bearings in opposite stands 14, 14, which aremade fast to the upper portions of the cheeks 2, 2. The shaft 9 of theroll 9 projects at its ends or journals into slots 14 in the saidstands,

and within each of the said slots a block 9 enable the rolls to beseparated from eachother whenever desired, a roll-separator is provided.In this instance it consists of a U-shaped frame 15 hung upon atransverse wire or rod 15 extending from one stand 14 to the other, thesaid frame having sidearms 15", 15*, which pass down alongside the endsof roll 9 and are formed with camportions 15, 15, which are disposed infront of the journals of such roll. A handle 15' is provided on theframe 15, by means of which the latter may be rocked to cause the camsto act against the said journals to'press the roll 9 away from the roll8, overcoming the resistance offered by the springs 9, 9. Thecam-portions 15, 15, are formed with projecting portions which actagainst the journals to prevent excess movement of the frame which woulddisengage the said camportions altogether from the journals.

The feed-rolls are rotated intermittingly automatically by. means ofsuitable actuating devices. Herein the said actuating devices comprise acrank 16 carried by shaft 3, connected by a rod 17 with a lever 18 hungupon Through the described devices an intermit-' tent movement ofrotation is transmitted naeaaee to the feed-roll 8 from the operatingshaft 3. The feed-rolls 8, 9, are geared together by spur-gears 19, 19,fixed upon their shafts so that they thereby positively are caused torotate in unison slip of oneroll relative to the other being avoided. Aneccentric friction-dog 18 mounted upon the adjacent stand 14 on the stemof a screw 18 and rotated by a spring 18, Figs. 2 and 3, to cause itseccentric portion to engage with the periphery of wheel 18", serves toprevent backward rotation of the feed-roll 8. To provide for varying theextent to which the strip a is moved along at each feed-movement, Iemploy a crank 16 of adjustable throw. In this instance the carrier 16of the crank- -pin is slotted lengthwise at 16 and secured to aface-plate 16 on one end of shaft 3 by means of a screw 16 passingthrough slot 16 into the said face-plate. This construction permits thecarrier 16 to be adjusted diametrically of the shaft 3 so as to enablethe crank-pin to be set at the distance from the axis of said shaft 3which is necessary to give the proper throw to secure the desired extentof feed-movement.

To hold the carrier 16 from turning rela tive to the face-plate, butstill permit of the adjustment of the carrier diametrically withrelation to the shaft 3, I may employ any convenient guiding arrangementin connection with the carrier face-plate. In the present instance pins16 16 are oppositely located upon the carrier and parallel slots 16',16*,are formed in the face-plate. These slots extend parallel with thediametrical line on which the crank pin is adjustable, and at oppositesides of the said line and the pins work in the said slots 16 16 Toenable the feed-rolls to be rotated manually for the purpose ofadvancing the strip a at will, the roll 8 is furnished with athumb-wheel 20, Figs. 2 and 3, fixed upon one projecting end-portion ofits shaft 8 lVhen it is desired to make a backward or reversed shift ofthe strip, the rolls are separated by means of the roll-separator so asto release their grip upon the strip and permit it to be adjusted byhand.

As the ram closes against the die the pulloff 7 operates to pull fromthe source of supply and through the guide-system A. a sufficient lengthof the strip afor the next feeding movement of the latter past the dieand as the "am separates from the die the pull-off slackens the stripwithin the machine concurrently with a feed-movement of the feed-rollsacting to draw the strip past the die. The pull-off and slackeningaction are provided for by mounting the ull-oif 7 upon the radius-arm orframe i the latter being linked at i? to the ram, as already explained,so as to he swung by the movements that are imparted to the ram.-Thereby the pull-cit is operated in unison with and by the ram. Eachmovement of rotation of the feed-rolls coincides with the slackening ofthe strip by the reverse movement of the pull-ofi, and consequently thefeed-rolls merely operate to draw forward die, so that such portionholds the strip a separated from the face of the die. The saidbacking-plate and guide is movably mounted, and to it are. givenmovements which at the time of the closing of the ram toward the die forthe impression cause the guide to recede relative to the die as in Fig.5 so as to carry the said strip close to the face of the die, or intocontact with such face; and subsequently, as the ram moves away from thedie after the impression, causes the guide to follow the ram part way soas to detach the strip from the face of the die and separate ittherefrom. lfhe further receding movement of the ram carries the latteraway from the strip, as shown in Fig. 4. For the movable mounting of theguide, the combined hacking-plate and guide 11 is supported pivotally at11 upon small stands 11*, 11

rising from the tops of the cheeks, 2, 2. The required movements arecommunicated to the backing-plate and guide, to rock the same upon itspivotal mounting, through connections between the same and theradius-arm or lever 4? of the ram 4. The said connections include a link11 extending from the rear portion of the combined backing-plate andguide to a portion of the radius-arm or lever a at the rear of its pivota. To provide for adjustment of the guide with reference to the die andthe front end of the die-support, the link 11 is made adjustable inlength by being formed in two parts or members which respectively arepivotally joined to the combined backingplate and guide, and radius-armor lever 4 respectively, and connected together by means of screws 11",11", one of the two linkmembers being longitudinally slot-ted to permitthe said members to be adjusted relative to each other so as to vary thelength of the link. By lengthening or shortening the link ii thedownturned end of the hide 11 is lowered or raised relative to the die.

Simultaneously with the receding movement of the ram and theaccompanying movement of the guide by which the strip a is separatedfrom the face of the die, and detached therefrom in case it should tendto embossed or printed, in case it should tend to adhere thereto. Afterthe feed movement by which the portion of the strip a which is to beused in making the next impression is Y brought into position betweenthe die and the ram, the strip is held taut between the pull-ofl" 7 andthe curved lower end of the guide. 11, so that thereby it is helddefinitely against displacement as by a draft of air or by contact ofthe Work therewith while the latter is being placed in position to beoperated upon.

A difliculty experienced in feeding a strip of some length between apair of feed-rolls is the tendency of the strip to work edgewiseprogressively in one direction or the other. I overcome this difficultythrough the employment of an automatic guide by which tendency of thestrip to swerve from the proper path is corrected. This portion of theinvention involves broadly the employment of automatic strip-guidingmeans controlled by the strip and acting to restore the latterautomatically to the proper path of travel in case it swerves from suchpath. In the illustrated embodiment of the invention the feed-roll 8 isarranged to counteract the said tendency. For the said counteraction, Iconstruct and combine the roll 8 and its supporting shaft or arbor 8 sothat when the strip a, in being fed, swerves toward one side or theother, the strip itself shall swing theroll into a position so inclinedrelative to the length of the strip that the rotation of the roll willcarry the strip automatically back into the proper path. Referring nowto Figs. 4, 5 and 6, it will be observed that in Fig. 6 the longitudinalbore that is made through the roll 8 for the reception of the shaft orarbor 8 is larger in'diameter than the portion of the latter whichoccupies the main length of the said bore, and that at midlength of theroll the shaft or arbor is formed with an annular enlargement 8* havinga transversely rounded periphery and resembling the middle zone of asphere. The portion of largest diameter of this enlargement fits thebore of the roll 8 at midlength of the roll. A screw 8 has its stemscrewed into the enlargement, while its rounded or ball-shaped headoccupies a radial hole 8 in the roll. The said head prevents the rollfrom displacement longitudinally of the shaft or arbor 8*, while theconstruction permits the roll to swivel relative to the shaft or arbor.In the operation of the machine, so long as the middle of the width ofthe strip a corresponds in position with the middle of the width of theenlargement 8", equal portions of its width of the portion of strip atthe side of the swiveling point toward which the strip has swerved willcarry the corresponding end of the roll 8 forward, thereby causing thesaid roll to swing into a forwardly in-- clined or angular position; Theresult of this will be that rotation of the roll in such forwardlyinclined or angular position will exert a tendency to cause the strip totravel back to the middle position again. In this way the roll Willautomatically guide the stri so that it normally will travel in thepredetermined path. The side-guides of the two guide-systems-A, B, arelocated at equal distances from the proper position for the middle lineof the strip, and inasmuch as the said guides, are arranged to moveequally in opposite directions from or toward said mlddle line in theiradjustments, and to remain parallel to each other in all their positionsof adjustment, the said 'adjustments have no disturbing effect upon thepath of travel of the strip which would interfere -with the attainmentof the desired results in automatically guiding the strip by means ofthe swiveling roll 8.

For some classes of work, the strip a of transfer material consists of astrip of paper treated with paraflin charged at one surface of the stripwith the gold or other printing substance. Proximity of the strip to theheater has the effect of softening the paraffin and decreasing its holdupon the gold or other printing substance. In other words "the effect ofthe heat from the heater is to render it easier for the gold,

or other printing substance, to strip from the paper-backing. The.result of this, in the absence of means to counteract this tendency, isa liability of the printing substance to strip from the backmg alongsidethe lines of the imprint made upon the leather or other work operatedupon. When the feed-movements of the strip are closely proportioned tothe size of the face of the die, so as to economize in the use of theprinting substance this stripping of the printing substance from thebacking alongside lines of the imprint upon the work will depriveportions of the backing within the limits of the next succeedingimpresslon of portions of their charge of the printing substance andconsequently the succeedlng imprint will be imperfect. To prevent thistendency, a cooling device is provided by means of which the softeningof the paraiiin is prevented. This cooling device comprises in thepresent instance a mouth-piece 20 arranged to discharge a stream of airupon the portion of the strip a which is adjacent the die and heater.The

said mouth-piece is shown arranged above the pull-off 7, and so as todirect the said stream upon the reverse side of the strip below theheater. The mouth-piece 20 is attached to a short pipe 20 carried by theradius-arm or lever i In practice, a conducting pipe or tube (not shown)will extend from the said pipe 20 to a pump (not shown) or other sourceof supply for air under pressure.

The illustrated machine is adapted for use in operating upon theinterior surfaces of the uppers of shoes by reason of the fact that thedie-support and the die are of width and proportions adapting them to bereceived within the top of an upper, and the strip a feeds from therear, forward past and around the die and the frontend of thedie-support, and then rearward relative thereto. If the said strip werefed laterally from a source of supply at one side or. the other of thedie and die-support, the portions of the strip stretching laterallyoutward from the die at one or both sides of the latter would interferewith the application of a shoe-upper to the machine for the purpose ofbeing embossed or printed.
